BUILDING BLOCK.

Application filed fiepteinber 27, 1922.

T 0 all whom it may concern:

Be it known that I, RICHARD Mummy, a citizen of the United States, and residing at New York city, in the county of New York and State of New York, have invented certain new and useful Improvements in Building Blocks, of which the following is a specification, such as will enable those skilled in the art to which it appertains to make and use the same.

This invention relates to building blocks and particularly to elongated rectangular blocks composed of cement, concrete and like material and of hollow construction formed by an enclosed chamber and an aperture opening outwardly through the brick or block; and the object of the invention is to provide a brick or block of the class specified, which is simple in construction, and comparatively light in weight and yet strong and durable in use, and which is constructed as hereinafter described and claimed.

The invention is fully disclosed in the following specification, of which the accompanying drawing forms a part, in which the separate parts of my improvement are designated by suitable reference characters in each of the views, and in which The drawing shows two views of a building block, made according to my invention, one view being a longitudinal, sectional view and the other an end view.

In the drawing, I have shown a brick or block 12 provided in one end portion thereof with an aperture or chamber 13., opening outwardly through one end of the block, and in the other end thereof with a closed chamber or compartment 1d formed by a box member 15 of inexpensive material, which is molded in the brick or block 12.

The brick or block shown in the drawing is designed particularly for use as an end or finishing brick in the construction of the walls of a building, the enclosed end portion of the brick or block being exposed,

thus avoiding the necessity of filling in or covering the open or exposed ends of a brick or block.

Serial No. 590,752.

It will also be apparent, that with the brick or block shown in the drawing, they may be split in halves or quarters, as is the usual custom in the construction of the walls of a building.

In the construction shown, the bricks or blocks are made light by the provision of bores, apertures, chambers or the like therein, for the purpose of providing chambers or passages between the inner and outer faces of said bricks or blocks in the use thereof in the construction of the walls of a building, and while I have shown certain methods of carrying my invention into effect, it will be understood that I am not necessarily limited to the specific form and construction of the building brick or block herein shown and described, and various changes therein and modifications thereof may be made within the scope of the appended claims without departing from the spirit of my invention or sacrificing its advantages,

Having fully described my invention, what I claim as new and desire to secure by Letters Patent, is

1. A building brick or block of the class described composed of an elongated rectangular body of suitable material having apertures therein, said apertures being subdivided substantially centrally of the brick or block, and a unitary box-shaped core piece in said body and forming one of said apertures.

1i buililing brick or block of the class described composed of a unitary, hollow core piece. a body of suitable brick forming material surrounding said core piece to form in the completed brick or block an entirely enclosed chamber, and said brick or block being provided with an aperture independent of said chamber and opening outwardly therethrough.

In testimony that I claim the foregoing as my invention I have signed my name this th day of Sept, 1922.

RICHARD MURRAY.
